I just acquired a 20 year old Taurus with a V6 and 186k miles on it.. very inexpensive "a to b" car. 2 of the spark plugs haven't been firing for who-knows-how-long, so four of the pistons look (reasonably) clean when I take out the spark plug and two are just crusty and gross. I don't know what amount of time they've been failing to spark, but the vehicle does have moments when it fires on all 6... about 5 of the 100 miles I've driven it to get it home & begin diagnostics/repairs.
I'm guessing it will need new O2 sensors & cats since those have been eating unburned fuel for a while...
So here's my question: after I repair the ignition problem will the combustion chamber tend to clean itself out? Or is that not a thing that happens?
Advice appreciated.
